Maintenance routines
General
After installation, check with the installer that the unit is
in perfect condition. Request that the installer shows you
the controls and functions so that you are fully aware of
how the installation should work and be maintained.
Operation
Electrical output is controlled externally by the heat pump.
This means that the electrical output is connected and
disconnected by the additional heater.
Venting
Regularly check that there is water in the system. Air can
remain in the system after installation and the radiators
and boiler should be bled again. After bleeding, the pres-
sure must be checked and water topped up if necessary.
Safety valve
The heating system's safety valve must be completely
sealed and not release any water. The safety valve must
be checked regularly, about 4 times a year. Perform checks
as follows:
1. Open the valve.
2. Check that water flows through the valve.
3. Close the valve.
Reset the pressure by filling with water.
Actions in the event of freeze risk
In the event of extreme cold, no part of the heating system
must be switched off, there is a risk of frost damage.
If a part of the heating system is thought to be frozen,
contact the installer.
If the heating system will not be used for an extended
period of time, the water should be drained and steps
taken to ensure that the immersion heater cannot be
started.
